(Cl. Lll8 2 Claims.

This invention relates to improvements in a combination recording device and automobile key ring, wherewith a complete record of gasoline and oil used, oil changes and grease jobs may be kept.

Another object of the invention is to provide an automobile key ring and recording device With which a complete record of fuel and lubrication may be kept and at the finger tips of the operatorin order that he will not be liable to forget to record each such service to his car.

A further object of the invention is to provide a combination drivers license case and recording device. Y

Other features and advantages will become more readily apparent from the following description and the accompanying illustrative drawings in which:

Figure 1 is a plan view of my invention,

Figure 2 is a longitudinal sectional View thereof,

Figure 3 is a transverse sectional view of the device,

Figure 4 is a detail perspective View of a cylinder and recording ring operable thereon, but shown spaced apart therefrom, and

Figure 5 is a partial sectional view through the end cap and its integral positioning flange and pin, said pin being shown in elevation.

Like reference characters indicate like parts throughout the following specification and in the accompanying drawings in which I 0, is my recording device, license holder and key ring combination, the outer tubular casing II, of which is of a convenient length to be held in the hand of a user as a carrier for a key ring l2, which in the present instance is shown to be iiexible in order that it may slide freely through a bore I3, passing through the one end I4 of the device.

The construction of the device is as follows: I 5, is a tube having a head I6, of enlarged diameter, through which is a bore Il. Frictionally, but rotatably mounted on the cylinder I5, is a series of numbered rings I 8, spacer rings I9, and a keeper ring 20. The rings I 8, are consecutively numbered upon the peripheral surfaces 2 I, thereof, from one to zero, and each number is separated from the next by a transverse slot 22. The case II, is mounted over the said series of rings, its bore I3, being aligned with bore I1, thus holding the casing from rotation through the passage of the chain ring I2, lthrough said aligning bores.

The casing II, is provided with a series of longitudinally aligning window openings 23, 24, and 26, under the first of which are exposed ve of the rings I8, under the' second windoW are exposed two of the numbered rings, under the window 25, are exposed five numbered rings and under window 2B, are exposed ve numbered rings. Provided on the casing directly over and under the window 23, are the Words Gasoline and Gals Similarly provided at window 24, are the Words Oil and Qtsf At Window 25, is the indicia Grease jobs, Mi., and at Window 25, Oil change, ML

Longitudinal flanged members 21 and 28, are provided along the edges 29 and 30, of all of the said window openings in casing II, and under which flanges is slidably seated a protective plastic strip 3|, preferably transparent. In the end 32, of the device is a cap 33, having an inner reduced annular iiange 34, adapted to t frictionally between the terminal ends 35 and 36, of the members Il and I5. Projecting centrally from the inner surface 31, of said cap is a pin 38, the point 39, of which is adapted to engage the slots 22, in the rings I8, whereby they may be rotated to bring the desired gures 4B, under the said windows 23 to 2B, respectively. Rolled within the tube l5, is a drivers license 4|.

By means of the rings I8, a convenient service record may be readily and easily kept, as gallons of gas used will be indicated under window 23, quarts of oil used through window 24, grease jobs per mileage through window 25, and oil changes per mileage through window 26. This arrangement will obviate the usual custom of placing stickers upon the car for such recording.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering vhe description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in shape, size and rearrangement of details and parts such as come within the purview of the invention claimed may be resorted to, in actual practice, if desired.

Having described my invention that which I claim to be new and desire to procure by Letters Patent is:

1. A device as described comprising ,-a cylinder of a length to receive a license card, a second cylinder within which the first cylinder is seated, said first cylinder having an enlarged head forming a spacer between the cylinders, a removable ring of the same diameter as said head adapted to form a spacer for the opposite end of the cylinders, a closure cap for the device provided with an inner integral flange adapted to be frictionally held between the open ends of the cylinders, a series of number carrying rings, spacer rings and a retainer ring mounted frictionally between the tubes, all of the rings being of a common thickness throughout the Width thereof and their entire transverse surfaces engaging the opposing Walls respectively of said cylinders whereby the rings will be held against accidental movement, certain of the rings having transverse grooves between the numbers thereon and means carried within the inner cylinder by said cap for rotating certain of the rings against said frictonal engagement.

2. A device as described comprising a cylinder of a length to receive a license card, a second cylinder Within which the first cylinder is seated, said rst cylinder having an enlarged head forming a spacer between the cylinders, a removable ring of the same diameter as said head adapted to form a spacer for the opposite end of the 4 cylinders, and a closure cap for the device provided with an inner integral flange adapted to be frictionally held between the open ends of the cylinders.
